We conducted a brief computer-based assessment involving choices of concurrently presented arithmetic problems associated with competing reinforcer dimensions to assess impulsivity (choices controlled primarily by reinforcer immediacy) as well as the relative influence of other dimensions (reinforcer rate, quality, and response effort), with 58…

The computerization of attention tasks has allowed clinicians to incorporate objective data into evaluations of attention deficit disorder or hyperactivity. The Gordon Diagnostic System (GDS) is described and case histories are presented which illustrate the contribution of GDS data to evaluation and treatment monitoring. (DB)

The ecological validity of the Conners' Continuous Performance Test II (CPT-II) was examined using a sample of 206 first- and second-grade children. Children's CPT-II scores were correlated with observations of inattentive/hyperactive behavior during CPT-II administration, observations of children's behavior during analogue academic task,…

This study examined the ability of a newly developed computerized visual vigilance measure, the Preschool Vigilance Task (PVT), to differentiate between 20 hyperactive and 20 control preschoolers. The PVT was developed to minimize cognitive requirements in a vigilance measure. The study compared performance of the subjects on the PVT and the…

The Raggio Evaluation of Attention Deficit Disorder (READD) is an objective measure for the diagnosis and management of attention deficit disorder (ADD) in children. Extensive research has been conducted on its clinical and psychometric properties, as described in Chapter 3, "Development and Standardization." The READD is a microcomputer…
